Max Malmquist stares into the southern fringe of Nice Salt Lake, his dad at his facet, eyes drawn in the identical course. That’s once they spot it: a Snowy Plover. Small and as sandy in coloration because the dry lakebed beneath it, the chicken is troublesome to see, however they’ve noticed it, nonetheless.
Max’s dad, Mike, attracts on a sheet of paper—a single mark for the one chicken.
It’s August at Nice Salt Lake which implies persistent bugs, rolling desert warmth, and most significantly, migrating shorebirds. Max and his dad have been out for the reason that early morning hours, early sufficient to catch the dawn and the setting of a full moon.
This, nevertheless, is what they’re right here for: the depend.
One other hundred or so volunteers unfold throughout the 1700 sq. miles of Nice Salt Lake and its related wetlands, strolling the shoreline whereas holding monitor of each shorebird, not simply Snowy Plovers. Together with them, quite a few biologists from the Utah Division of Pure Sources and different state and federal companies traverse the shoreline on ATVs, boats, and even by aircraft. Past Nice Salt Lake, shorebird surveys are additionally occurring at Salton Sea in California, Lake Abert in Oregon, the Lahontan Wetlands in Nevada, and greater than 200 different websites all through the Nice Basin.
Thirty years prior, a virtually an identical scene was taking part in out.
. . .
The extra data we’ve got in regards to the actions of shorebirds and their numbers, the higher geared up we’re to handle the essential ecosystems they rely upon and defend their populations for generations to return. On the subject of shorebirds although, buying such a stage of strong data is just not a simple job.
Many shorebirds will make the most of the complete hemisphere yearly. Within the winter they’re unfold throughout the tremendously huge landscapes of North, Central and South America, and all through the breeding season, they’re dispersed throughout the Arctic and different extraordinarily distant areas. It’s almost not possible to get a complete image of shorebird populations throughout these instances, leaving birders and biologists one alternative—migration.
“Migration offers us with this distinctive state of affairs the place important parts of shorebirds are funneling by way of a extra outlined panorama, offering us with the chance to actually get an concept of how they’re doing,” Max, Engagement Supervisor for Audubon’s Saline Lakes Program and lead coordinator of the Intermountain West Shorebird Surveys, defined.
The catch? Peak migration intervals are quick, lasting just one to 2 weeks—that means it takes a herculean effort to depend shorebirds throughout 200+ websites within the Intermountain West in such a short window of time. And that is as true right now because it was 30 years in the past, over the past surveys of this scale.
Again within the Eighties, Level Reyes Chook Observatory, identified right now as Level Blue Conservation Science, was conducting the Pacific Flyway Mission, overwintering populations of shorebirds alongside the coast. By way of these surveys, biologists have been in a position to determine a essential hole within the knowledge: inland habitats all through the Intermountain West.
Constructing off the momentum of their Pacific Shorebird Surveys, Senior Scientist, David Shuford and his staff at Level Reyes, undertook the large effort of conducting the primary complete inland shorebird surveys inland wetland websites throughout the Nice Basin.
Utilizing the experience of the state and federal biologists who aided on this effort, 162 websites throughout the Nice Basin have been recognized as doubtlessly essential to shorebirds.
Between 1989-1995, volunteers spent intervals of fall and spring migration on the bottom throughout these 162 websites counting shorebirds to ascertain the relative significance—38 of the websites supported greater than 1000 shorebirds every year.
Max had the pleasure of assembly David Shuford in 2023 at the Mono Lake Chook Chautauqua. He requested David how he was in a position to set up such an expansive effort, to which David laughed and solely mentioned, “A variety of telephone calls.”
But the telephone calls paid off. On the finish of these 5 years, for the primary time ever, the group had a profound understanding of shorebirds—what number of there are, the place they go, and the locations they rely upon all through the Nice Basin. The outcomes of that historic effort culminated within the peer-reviewed article in Western Birds Journal, Patterns of Distribution and Abundance of Migratory Shorebirds in the Intermountain West of the United States.
Since its publication, the information from this historic research has knowledgeable years of labor and decision-making for conservationists, biologists, state companies, non-profit organizations and extra. To today the knowledge remains to be broadly referenced, regardless of drastic environmental modifications. Within the final 30 years, between local weather change, drought, and elevated water diversions, most of the wetlands and shorebird habitats initially surveyed have undergone important transformation or fully disappeared.
“Shorebirds are a gaggle of species which are of biggest conservation concern as a result of they’ve seen declines primarily based on all of these elements,” Max mentioned. “That was what led to those historic surveys—the necessity to perceive how shorebirds’ populations are doing, and likewise what wetlands habitats they depend on.”
And the necessity right now is even larger as we’ve lost 3 billion birds across North America since 1970.
. . .
Understanding how essential Shuford’s unique knowledge assortment proved to be, and the 30-year knowledge hole since its publication, Stan Senner, former Vice President of Chook Conservation with the Nationwide Audubon Society and Brad Andres, from the Division of Chook Habitat Conservation at U.S. Fish and Wildlife Service, set in movement the rejuvenation of these surveys by way of the Pacific Flyway Council, leading to one other five-year surveying effort: the Intermountain West Shorebird Surveys.
August 9, 2022, marked the trouble’s pilot surveys as over 200 contributors throughout eight western states surveyed for shorebirds at 88 websites from the unique research. In 2023, the undertaking expanded to over 300 contributors, and included the unique 162 websites, plus extra websites newly recognized by biologists as essential to shorebirds. These additions have expanded the scope of the undertaking to incorporate the easternmost portion of the Pacific Flyway in Colorado, New Mexico, Wyoming and Montana.
It’s no simpler right now to survey these websites than it was 30 years in the past.
“We’ve moved from telephone calls to emails, but it surely nonetheless takes a substantial quantity of effort and group to mobilize such numerous volunteers and biologists so we will make these surveys occur,” mentioned Max.
Whereas the coordination effort would possibly look barely completely different, the surveying work itself has remained the identical: devoted volunteers on the bottom, recognizing scopes and binoculars in hand, counting shorebirds at their survey web site, on foot, in boats, or scouting by planes at some areas, for hours throughout peak migration days.
One of many primary objectives of procuring this new knowledge is to take a retrospective look to see how populations of shorebirds and their distribution throughout these wetlands have modified during the last three a long time. As well as, this effort seeks to grasp how the wetlands themselves have modified. Everybody collaborating within the efforts right now understands how essential the work is that they’re doing.
“If we will determine particular species and websites which are struggling, wetland managers may have the knowledge they should inform their administration of the land and prioritize sustaining meals, habitat, and sources for these particular species of birds,” Max defined.
There have been three seasons of surveys up to now together with the pilot surveys in Fall 2022, and one other 4 seasons scheduled. By way of the surveys thus far, we’ve found that most of the websites recognized as essential previously proceed to be simply as essential right now, however others have been severely degraded. And with regards to birds, the retrospective comparisons of the depend are already proving important.
Regionwide Comparisons:
Beneath are among the preliminary outcomes medians, ranges and complete uncooked counts in comparison with the unique research outcomes from David Shuford and Level Reyes (Level Blue):
Fall Migrations 1989-1995 (Shuford et al, unique research) | 670,953 (median) *162 websites
Fall Migration 2022 | 366,659 (complete uncooked depend) *88 websites
Fall Migration 2023 | 727,578 (complete uncooked depend) *211 websites
The numbers show much more attention-grabbing if you break it down by species in location. Contemplate the American Avocet at Nice Salt Lake:
Fall 1989-1995 Median & Ranges (Shuford et al, unique research): 220,272 (25,785-252,358)
Fall 2022 & Fall 2023: (25,399 & 51,362)
Or Phalaropes at Nice Salt Lake:
Fall 1989-1995 Median & Ranges (Shuford et al, unique research): 65,579 (620-111,277)
Fall 2022 & Fall 2023 Ranges: (165,078-203,255)
After all, anybody analyzing these preliminary outcomes should take into account a couple of key issues: preliminary outcomes don’t account for variations within the complete space surveyed and the websites range in measurement vastly, shorebird counts throughout migration can range daily, and the outlier climate skilled throughout the first three surveys.
The Fall 2022 Surveys have been taken within the thick of the West’s megadrought with key websites resembling Nice Salt Lake at historic lows, whereas the Spring 2023 Surveys noticed record-breaking snowpack and spring runoff throughout the West.
“The primary three seasons of this program have been reverse ends of the spectrum—the extremes,” Max mentioned, highlighting that the explanation these applications run 4 to 5 years is to assist guarantee we seize knowledge from extra typical seasons.
“After we began this undertaking in August 2022, Jap Nevada’s historic websites have been fully dry and appeared like they might by no means have water once more. Then, after final 12 months’s climate cycles, the identical websites instantly had shorebirds and supplied habitat once more.” he mentioned. Water ranges have been so excessive at some websites that Spring 2023 surveys couldn’t even be performed.
“We are going to take that under consideration after we do our evaluation.”
Whereas there are nonetheless a couple of years earlier than the survey will end—and Audubon, Level Blue and others will publish one other peer-reviewed manuscript with the 30-year retrospective look—sharing preliminary outcomes as they turn out to be accessible has turn out to be a high precedence.
“Contemplating how shortly situations are altering at Nice Salt Lake and different websites, there has already been a big request and have to get knowledge sooner. After every year or season of surveys, we’re working to have faster output of seasonal knowledge and experiences in order that the proper individuals can use this data to assist shorebirds.” Max mentioned.
Janice Gardner, Govt Director and Conservation Ecologist with Sageland Collaborative, in partnership with Max and Nationwide Audubon Society’s Saline Lakes Program, has organized and delivered seasonal reports and updates on the findings at Nice Salt Lake. Level Blue’s lead on the undertaking, Blake Barbaree, has additionally been sharing outcomes on a regional scale as they turn out to be accessible. In an ongoing and complimentary undertaking, Level Blue will quickly publish the primary ever inhabitants developments for the Pacific Flyway utilizing knowledge collected since 2012 from a winter monitoring program in all 13 countries of the Pacific Coast of the Americas. The outcomes from these experiences (and related ones) are gaining consideration.
For example, Nice Salt Lake and Salton Sea have been the 2 most essential websites within the area for shorebirds thirty years in the past. These two websites stay most essential—on a single day throughout Fall 2023 migration, surveyors counted 250,000 shorebirds at Salton Sea. That’s greater than twice the earlier most of 105,000 counted in Shuford’s unique surveys.
These conversant in the area know that this shorebird improve isn’t the one important change occurring on the Salton Sea. Quickly declining water ranges have resulted in shallower water habitats and elevated salinity, ideally suited for shorebird populations whereas devastating for different chicken species, and situations at Salton Sea are persevering with to vary at an alarming charge.

On the core of each set of outcomes, one factor is evident: over millennia, shorebirds have developed to reap the benefits of little niches and unimaginable wetland habitats throughout the Intermountain West. However they will solely evolve so shortly, particularly within the face of fast climactic modifications. That means time is of the essence with regards to finishing these surveys, publishing their findings, and letting their outcomes inform our work to make sure these species may have the chance to proceed migrating by way of wetland habitats.
“Whether or not we imply to or not, we’re dropping lots of these habitats and we’re having an influence on these shorebirds and their populations. Collaborating in these surveys is a novel alternative to be concerned within the conservation of those birds and doing every part we will to make sure that they will exist sooner or later.” Max mentioned, reflecting that his personal time surveying has helped to tell his love for this undertaking.
We all know from analysis that defending and sustaining wholesome wetlands additionally protects communities, public well being, leisure alternatives, ecological capabilities and even the financial pursuits of surrounding communities. It begins with the birds, however the optimistic suggestions loop of conservation and habitat safety extends a lot additional.
The Spring 2024 surveys will run from April 24-30. To enroll as a volunteer, contact Max Malmquist or Blake Barbaree for upcoming survey alternatives and different methods to be get entangled: max.malmquist@audubon.org and bbarbaree@pointblue.org.
